Definitions

  • the present invention relates to a process of electroforming a metal product, more particularly a screen, by subjecting a first thin product skeleton formed upon a matrix in a first electrolytic bath and subsequently stripped from the matrix, to an electrolysis in a second electrolytic bath, comprising at least one organic compound improving the growth of metal in a direction substantially perpendicular to the plane of the skeleton.
  • a process of this type for electrolytically forming a screen has been used in the art and is disclosed in NL. S No. 80,021,97.
  • a first thin screen skeleton is formed by electrodepositing nickel metal upon the ribs of a steel plate comprising recesses filled with a di-electric material, e.g. bituminous material.
  • the separating ribs Prior to stripping the formed first screen skeleton from the matrix and to facilitate said stripping, the separating ribs are provided with a layer of beeswax as a separating means.
  • said first thin screen skeleton is thickened in a second electrolytic bath at least comprising one organic compound to improve a metal growth, in a direction substantially perpendicular to the plane of the screen to obtain the desired screen.
  • the screen as formed suffers from a number of drawbacks, getting the more serious in case of more or less differing properties between the deposited metal layer and the screen skeleton, but even when identical metals are being used, the following shortcomings will arise:
  • the final screen has an a-symmetrical building up of materials, resulting in different properties inherent therewith, such as ductility and corrosion resistance. In addition thereto the optical appearance of said screens is imperfect;
  • first skeleton thickened in the second electrolytic bath is subjected to an electrolysis in at least one other electrolytic bath, also comprising an organic compound improving growth of metal on the outer surface of the thickened skeleton in a direction substantially perpendicular to said outer surface.
  • a surface layer is deposited upon the skeleton as obtained from the second bath of a metal identical to that deposited on the first thin product skeleton, more particularly a screen skeleton.
  • a screen can be obtained, having two surfaces of the same desired metal, the metal layer disposed thereinbetween and deposited in the second electrolytic bath, consisting of a metal entirely different from that of the metal of the thin product skeleton and the surface layer.
  • the use of a particularly flexible metal for said intermediate layer will result in screens having great mechanical stength properties and, in addition thereto, optimum properties with a view to the properties of the metal surface layer.
  • a metal is deposited upon the skeleton with a hardness greater than that of the metal as deposited in the first electrolytic bath or other electrolytic bath(s), respectively.
  • a tin-nickel alloy in the other or third electrolytic bath, nickel being deposited in the first electrolytic bath and iron in the second bath.
  • Nickel-iron can also be used for the second bath. In this manner a screen is obtained which is also particularly resistant to mechanical damages, due to the relatively easily deformable tin-nickel material which has been deposited in the other electrolytic bath(s).
  • a first, a second and another electrolytic bath are used, in which one and the same metal, possessing different properties, if any, is deposited constantly.
  • This embodiment also provides a screen having better properties than a screen obtained from a first product skeleton obtained by using a first and second electrolytic bath from which identical metals are deposited.
  • the present invention also comprises a metal product, more particularly a screen skeleton, comprising a first electrolytically formed product skeleton and a layer deposited electrolytically from a second electrolytic bath, in which the edges of the metal product, more particularly the edges of the apertures in a screen, are substantially free from metal deposited in the second electrolytic bath and free from metal deposited as a top layer from at least one other electrolytic bath or baths.
  • the organic compound improving or facilitating a growth of metal in a direction substantially perpendicular to the outer plane of the skeleton is preferably an organic compound at least comprising a double or triple bond not belonging to a ⁇ C--S ⁇ O group and presenting properties of a second class brightener.
  • a nickel layer is deposited, after the recesses have been filled with a di-electric material, for example bitumen and the ribs have been provided with a thin layer of beeswax.
  • a thin first nickel screen skeleton is formed having a thickness of 20 microns.
  • the formed first nickel product or screen skeleton is subsequently stripped from the metal matrix and disposed in an electrolytic iron bath having the following composition:
  • the bath contains less than 0.02 gr/l of ferric ions.
  • the iron bath additionally comprises an organic compound facilitating the selective growth of metal in a direction perpendicular to the plane of the first screen skeleton.
  • said compound consists of hydroxy-proprionitrile in a quantity of 0.1-100 mmol/l, although use can also be made of, e.g., ethylenecyanohydrin.
  • the electrolysis proceeds at a temeprature of 70° C., a pH comprised between 3.8 and 4.2 and a current density in the range of 5.0 to 20.0 A/dm 2 . Electrolysis is continued until an iron layer has been deposited with a thicness of about 160 microns.
  • the obtained screen skeleton comprising the deposited iron layer is subsequently disposed in another electrolytic Watt's bath and provided with a nickel top layer by electrolysis, until a layer of 20 microns thickness has been disposited.
  • a screen consisting of two nickel surfaces, both having a thickness of 20 microns and of an intermediate iron layer with a thickness of 160 microns.
  • Said screen possesses excellent properties.
  • the flow through the apertures of the screen skeleton proceeds with a velocity in the range of 0.1 to 5.5 cm/sec.
  • a first thin nickel screen skeleton is produced in a manner as described in example I.
  • an iron layer is deposited upon the first screen skeleton, after the same has been stripped from the metal matrix; said iron layer having a thickness of 160 microns, whereas the initial screen skeleton possessed a thickness of 20 microns.
  • the iron bath also comprises an organic compound improving the growth of metal in a direction perpendicular to the plane of the screen skeleton, the organic compound being in this case ethylenecyanohydrin, although the use of hydroxyproprionitrile will also produce the same results.
  • a tin-nickel layer is subsequently deposited upon the abovementioned iron layer.
  • a first nickel screen skeleton having a thickness of 20 microns, is formed in a manner corresponding to example I.
  • said screen skeleton After having stripped the first skeleton from the matrix, said screen skeleton is disposed in an electrolytic nickel-iron bath.
  • the screen skeleton then provided with a nickel-iron layer with a thickness of 160 microns is finally disposed in a third electrolytic bath, containing a nickel alloy, for example, a thin-nickel alloy.
